label binding trouble

Hey Guys...So i'm attempting to use a label to display a record I have stored in a table in the DB. There is only one record in this table.

//declare class at top of page

     protected Invoice invoice_Info;
    
       myDataBase db = new myDataBase();
            
       invoice_Info =
                (from invoiceInfo in db.Invoice_Infos
                 select invoiceInfo).FirstOrDefault();
            
                    labelBindforInvoiceDetails.DataBind();

Then in my aspx page I am using:

    <span>                             
     <asp:Label id="labelBindforInvoiceDetails" runat="server" Text="<%# Bind('invoice_Info') %>"/>                                  
     </span>

But the code is throwin me an error with 'bind' Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
